Connecting blocks are arranged in the middle of both sides of the middle movable frame 7, and the connecting blocks are arranged in the slide grooves on the left and right sides of the lifting frame 5, and the middle of the connecting blocks is penetrated by the first screw rod 6. The first screw rod 6 is screwed to the connecting blocks in the middle of both sides of the middle movable frame 7, and the connecting blocks are horizontally slidably connected to the internal slide grooves on both sides of the lifting frame 5, and the rear end of the first screw rod 6 is rotatably connected to the rear inner wall of the slide groove.

[0045] Step 3: Rotate the second screw rod so that the movable frames on both sides of the middle movable frame spread outward or shrink inward with the middle as the reference, so as to accurately adjust the distance between the movable frames;

[0046] Step 4: Slide the movable block horizontally so that the movable block slides in the guide rail to above the part of the substrate to be cut, and control the horizontal sliding distance of the movable block;
